Verdict
The clearest difference is rating: Clusterduck at 4.8 against Sisyphos's 4.1. Clusterduck also leads on ratings volume (174K vs 389) and update cadence (fortnightly vs every 2 months). Sisyphos's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
